Circular yoke sweaters are quite popular now, some knitters make them with colour work, various stitch patterns but some use just plain stockinette fabric. It is quite fun. In Summer I made one for Marianne's Mohair (see picture in the bottom).
Now we can do it together: if you wish, join KAL on Ravelry (you have to register there). If you join, you will get the pattern from me and you can discuss everything in the forum thread. The name pf the sweater is 16 sts sweater. You will learn why when you will have joined the KAL. My yarn is mohair 50 g/200 m but you can combine several thinner yarns. All details in the forum thread.
